When you go gsp tank again, could you try to take accurate measurements of the length of those puffers again? I would like to report back to the puffer community about your findings. Generally, Tetraodon Sabahensis are around 6inches (usually) maximum. If you're saying they are 1ft long, then its a significant finding. Also, find out the water condition (ie Brackish or salt? tank size? ect).

I can stop by there again but it's a little over an hour away. They were over a foot long I'll measure them more closely next time I go there, will be there probably Sunday. It was strictly fresh water they were in no salt, I'd have to say the tank was at least a custom 100 gallon tank. But I will get specifics for you.
